Bandwidth - Audio• 44.1 kHz, 16-bit

44,100 x 16 = 705.6 kbps -> 1,417 ch/1 Gb link

• 48 kHz, 24-bit48,000 x 24 = 1.152 Mbps -> 868 ch/1 Gb link

• 96 kHz, 24-bit96,000 x 24 = 2.304 Mbps -> 434 ch/1 Gb link

Bandwidth - Video• 1080p/60

1920 x 1080 x 3 x 10 x 60 = 3.73248 Gbps

• UHD (3840 x 2160)3840 x 2160 x 3 x 10 x 60 = 14.92992 Gbps

• True 4K (4096 x 2160)4096 x 2160 x 3 x 12 x 60 = 19.1102976 Gbps

Bandwidth - Video• 4K60 4:4:4

• 4K60 4:2:04096 x 2160 x 1.5 x 12 x 60 = 9.5551488 Gbps

Compression• Audio – no compression needed

Compression• Audio – no compression needed• Video – may require compression

– 4K60 4:4:4 -> ~20:1 (1Gb), <2:1 (10Gb)– 4K30 4:4:4/4K60 4:2:0 -> ~10:1 (1Gb), 1:1 (10Gb)

Compression• Audio – no compression needed• Video – FHD and above require compression• CBR vs. Adaptive/Dynamic BR

Latency• Encoding + Network + Decoding

Ethernet Switch

Streaming Formats• Trade-offs:

Latency

Compression

Quality/Cost

Streaming Formats• H.264/H.265• JPEG2000• Dante (https://audinate.com/products/dante-enabled/partners)• AES67• Q-LAN• ST 2110• 802.1BA (AVB) (https://avnu.org/our-members/)• NDI• SDVoE (https://sdvoe.org/alliance/members/)

Control• Software-defined• APIs

Control & Management

Control & Management•Configure channels as public or private on your network•Group systems, devices, and applications to preference•Connect to and access channels on other networks via IP address•Connect to and access channels on other networks via IP address•Advanced tab allows preference for TCP or UDP connections, multicast operation, and optional discovery server support

Summary• Commercial AV systems moving to AVoIP solutions for

network transport and virtual switching• Audio can be transported without compression• High resolution video often needs to be compressed• Choose codec/streaming solution based on application

(tolerance for compression & latency)• HW & SW codecs, and software control, management &

tools allow for an end-to-end digital solution
